Abstract
An integrated slurry hydrocracking process and apparatus are described. The process includes introducing heavy residual hydrocarbon oil and a hydrogen stream into a slurry hydrocracking zone. The hydrocarbon feed is cracked to form a slurry hydrocracking effluent. At least a portion of the shiny hydrocracking effluent is introduced to a distillate hydrotreater along with make-up hydrogen. The slurry hydrocracking effluent is hydrotreated to form a hydrotreated effluent. The hydrotreated effluent is separated into a liquid stream and a gas stream containing hydrogen. The gas stream containing the hydrogen is recycled to the slurry hydrocracking zone forming the hydrogen stream introduced into the slurry hydrocracking zone.
